node-fetch is a lightweight library that provides a fetch()-like API for making HTTP requests in Node.js.
It is a light-weight implementation of the Fetch API, which is mostly compatible with the browser's version.
node-fetch is primarily known as almost identical package fetch() is included in web browsers so it
shares the same use common API. It's great starting point for people coming from front-end environment.
hrequests is a feature rich modern replacement for a famous requests library for Python.
It provides a feature rich HTTP client capable of resisting popular scraper identification techniques:
- Seamless transition between headless browser and http client based requests
- Integrated HTML parser
- Mimicking of real browser TLS fingerprints
- Javascript rendering
- HTTP2 support
- Realistic browser headers
```javascript
const fetch = require('node-fetch');
// fetch supports both Promises and async/await
fetch('http://httpbin.org/get')
.then(res => res.text())
.then(body => console.log(body))
.catch(err => console.error(err));
const response = await fetch('http://httpbin.org/get');
// for concurrent scraping Promise.all can be used
const results = await Promise.all([
fetch('http://httpbin.org/html'),
fetch('http://httpbin.org/html'),
fetch('http://httpbin.org/html'),
])
// POST requests
await fetch('http://httpbin.org/post', {
method: 'POST',
headers: { 'Content-Type': 'application/json' },
body: JSON.stringify({ name: 'John Doe' }),
})
// Proxy use:
const agent = new https.Agent({
rejectUnauthorized: false,
proxy: {
host: 'proxy.example.com',
port: 8080
}
});
await fetch('https://httpbin.org/ip', { agent })
// setting headers and cookies
const headers = new fetch.Headers();
headers.append('Cookie', 'myCookie=123');
headers.append('X-My-Header', 'myValue');
await fetch('https://httpbin.org/headers', { headers })
```
hrequests has almost identical API and UX as requests and here's a quick overview:
```python
import hrequests
# perform HTTP client requests
resp = hrequests.get('https://httpbin.org/html')
print(resp.status_code)
# 200
# use headless browsers and sessions:
session = hrequests.Session('chrome', version=122, os="mac")
# supports asyncio and easy concurrency
requests = [
hrequests.async_get('https://www.google.com/', browser='firefox'),
hrequests.async_get('https://www.duckduckgo.com/'),
hrequests.async_get('https://www.yahoo.com/'),
hrequests.async_get('https://www.httpbin.org/'),
]
responses = hrequests.map(requests, size=3) # max 3 conccurency
```
